Study on the grafting of chitosan–gelatin microcapsules onto cotton fabrics and its antibacterial effect

In this work, patchouli oil embedded chitosan-gelatin microcapsules were prepared by the complex coacervation method. Their surface and morphology were characterized by scanning electron microscopy (SEM), showing that the microcapsules were with a regular spherical shape in the range of 1 and 20 μm. In the thermal stability analysis, the microcapsules were stable below 190°C, which indicated the fabrics finish can be conducted at 160°C. The...
